Embodiment 1

[0017] Embodiment 1, a kind of preparation method of inorganic biodegradable adhesive tape,

[0018] Step 1. Get 50 parts by mass of calcium carbonate mineral powder, 30 parts by mass of polypropylene, 3 parts by mass of auxiliary agent and 1 part by mass of antibacterial agent and add in the mixer to mix for 40 minutes at a rotating speed of 150r / min to obtain a raw material mixture ;

[0019] Step 2. The raw material mixture is continuously banburyed in an extruder, and the temperature is controlled at 220°C. After the raw material mixture is melted, it is extruded into a strand, and after extruding, it is rapidly cooled in water and pelletized at a high speed, and then dehydrated and dried. Antibacterial masterbatch is obtained;

[0020] Step 3, get 90 mass parts of calcium carbonate ore powder and add it to the high-speed mixer, the speed is 800r / min, the temperature is 150 ℃ to carry out dehydration treatment for 8min, then 10 mass parts of composite surface active coupl...

Embodiment 2

[0028] Embodiment two, a kind of preparation method of inorganic biodegradable adhesive tape,

[0029] Step 1, get the calcium carbonate mineral powder of 60 mass parts, the polypropylene of 40 mass parts, the auxiliary agent of 4 mass parts and the antibacterial agent of 2 mass parts and add in the mixer and mix 42 minutes with the rotating speed of 165r / min, obtain the raw material mixture ;

[0030] Step 2: The raw material mixture is continuously banburyed in an extruder, and the temperature is controlled at 250°C. After the raw material mixture is melted, it is extruded into a strand, and after extruding, it is quickly put into water for rapid cooling, high-speed dicing, and then dehydrated and dried. Dry to obtain antibacterial masterbatch;

[0031] Step 3, take 95 parts by mass of calcium carbonate mineral powder and add it to the high-speed mixer, the speed is 1000r / min, the temperature is 165 ℃ to carry out dehydration treatment for 10min, then 11 parts by mass of th...

Embodiment 3

[0039] Embodiment three, a kind of preparation method of inorganic biodegradable adhesive tape,

[0040] Step 1, get 70 mass parts of calcium carbonate mineral powder, 50 mass parts of polypropylene, 5 mass parts of auxiliary agent and 3 mass parts of antibacterial agent, add in mixer and mix 45 minutes with the rotating speed of 180r / min, obtain raw material mixture ;

[0041] Step 2. The raw material mixture is continuously banburyed in an extruder, and the temperature is controlled at 280°C. After the raw material mixture is melted, it is extruded into a strand, and after extrusion, it is quickly cooled in water, and is diced at a high speed, and then dehydrated and dried. Dry to obtain antibacterial masterbatch;

[0042] Step 3, take 100 parts by mass of calcium carbonate mineral powder and add it to the high-speed mixer, the speed is 1200r / min, the temperature is 180 ℃ to carry out dehydration treatment for 12min, then 12 parts by mass of the composite surface active cou...

Abstract

The invention discloses and relates to a preparation method of an inorganic biodegradable adhesive tape. The prepared adhesive tape is good in air permeability, has a good antibacterial effect, is degradable, is high in strength, can be used for replacing a traditional disposable plastic adhesive tape, and reduces pollution.

Description

technical field [0001] The invention relates to a preparation method of an inorganic biodegradable adhesive tape. Background technique [0002] At present, the tapes on the market are made of plastic substrates. The adhesive tape is usually based on polypropylene film, which is uniformly coated with pressure-sensitive adhesive emulsion after heating to form an adhesive layer. As an indispensable product in light industrial enterprises, companies and personal life, tapes include sealing tapes, art tapes, cleaning tapes, medical tapes, stationery tapes, and vegetable and fruit food packaging tapes. However, in the treatment of such tapes, incineration is generally performed, and objects such as inhalable particles, acid gases, dioxins, and organic poisons cause pollution to the environment. [0003] In order to reduce environmental pollution, degradable adhesive tapes are required to replace disposable plastic adhesive tapes, and in order to adapt the adhesive tapes to vario...
